Application filed March 28, 192?. fierial No. 178,829.

Qutlet boxes often have achcd. to them certain wpiipnient, such as electric switches. It is desirable to attach these to the outlet box and such equipment is commonly supplied with perforations ior screws for attaching them. These openings are not standardized and it is desirable to provide an attaching means which may take up the slight variations in size. The present invention is designed to accomplish this result in a simple and efiicient manner. Features and details oi the invention will ZLPPCZU from the specification and claims.

A preferred excmplilication of the invention is illustrated in the accompanying drawings as follows:-

Fig. 1 shows a side elevation, partly broken away to better show construction.

Fig. 2 a plan View of the device in connection with an outlet box.

Fig. 3 a section on the line 3-3 in 2.

Fig. 4 a plan View of one of the attaching plates. 1

Fig. 5 a side elevation of the same.

Fig. 6 a plan view of the companion plate.

Fig. 7 a side elevation of the same.

1 marks an outlet box into which conduits 2 are led, the conduit receiving extensions 3 being of usual form.

The box has an opening 4 at the side surrounded by a flange 5. This flange is provided with a radial slot 6. Structures of this type are not uncommon.

The attaching device comprises two plates 7 and 8. The plate 8 has an oil-set 9 through which there is an opening 10. The plate 7 telescopes through the opening 10. The plates 7 and 8 have slots 11 and 12 and screw-threaded openings 13 and 1d. The slots are in the upper portions of the device when it is assembled and the slots are directly above the screw-threaded openings 13. The screw-threaded openings are adapted to receive screws 11) which are used to secure electric equipment to the box. As shown this is in the form of an ordinary switch.

The openings in the equipment vary in distance from the center and the telescopic arrangement of the bars permits slight variations in this distance. Further the bars are provided with a plurality of threaded openings which afford a wide range of adjustment.

In assembling the part, one end is hooked pndcr the flange as shown in Fig. l and the opposite end is dropped through the slot 6. The part is then turned to the position shown 2 the screws tightened in place, the bar assuming the position shown in Fig. 3.

Flhat T claim as new is 1. in an attaching device for outlet boxes, the combination of two telescopically connested plates, one end of each plate being superimposed by the other and superimposing the other plate at the opposite end, each plate having its superimposing end slotted and the end which superimposed provided with a screw-threaded opening, the screwthreaded openings being below the slots.

2. Tn an attaching device for outlet boxes, the combination of two plates, one plate passing through the other and one end of each plate being superimposed by the other and superimposing the other plate at the opposite end, each plate having its superimposing end slotted and the end which is superimposed provided with a scrcw-threaded opening, the screw-threaded openings be ing below the slots.

3. In an attaching device for outlet boxes, the combination of two plates, one plate having an oil-set portion with an opening therethrough and the other plate extending through said opening, one end of each plate being superimposed by the other and super imposing the other plate at the opposite end, each plate having its superimposing end slotted and the end which is superimposed provided with a screw-threaded opening, the screw-threaded openings being below the slots.

4. The combination of an outlet be having an annular flange, and an attaching device comprising two plates telescopically connected, one end of each plate being superimposed by the other and superimposing the other pla'te at the opposite end, each plate having its superimposing end slotted and the end which is superimposed provided with a screw-threaded opening, the screwthreadcd openings being below the slots.

5. The combination of an outlet be having an annular tango, and an attaching device comprising two plates, one plate passing through the other and one end of each plate being superimposed by the other and superimposing the other plate at the opposite end,

each plate having its superimposing end slotted and the end Which is superimposed provided with a screw-threaded opening, the serew-threzuled openings being below the slots.

6. The con'ibination'oi an outlet box havingan annular flange, and an attaching device comprising two plates, one plate having an off-set portion with an opening therethrough and the other plate extending through said opening, one end of each plate being superimposed by the other and superimposing the other plate at the opposite end, each plate having its superimposing end slotted and the end which is superimposed provided with a screw-threaded opening, the screw-threaded openings being below the slots.

In testimony hereof I have hereunto set my hand.
